Vessel Calculation for Central Heating Systems
boilers are protected to a minimum working pressure of 0.8 or 1 bar. If such a pump or boiler is built in to a central heating system with a low static height, it may be more sensible to set the initial pressure of the expansion vessel to 1 bar rather than 0.5 bar. Note that the increased initial pressure does not

Pressure safety valve theory and PSV valve mechanism
The maximum allowable working pressure (MAWP) for the most of the boilers is 10 bar. That is, the pressure of the steam in the boiler can not go above 10 bar. The purpose of the safety valve, then, is to prevent the pressure in the boiler from climbing above its MAWP.
